As I’m sure you folks all know, history is rife with treatments and scripts for ultimately unproduced sequels for Godzilla, King Kong, and, of course, the Universal movies. This went to a first draft script and was bandied as a follow-up to Frankenstein Meets the Wolf Man. It was considered as (a terrible idea) a Technicolor film (!), and would have brought together Lon Chaney Jr and Bela Lugosi in the titular roles, quite a while before Abbott & Costello Meet Frankenstein.
There’s a wonderful series of books printing the scripts for the various Universal horrors, including unproduced drafts and scripts like this one. You can buy it on Amazon if you’d like.
Have a wonderful holiday weekend, everyone. Watch something stupid.
